g Be it known thctl, .Geenen W. JAcnsoN, s citizen of the United States, end e resident of Chicago, in the county of @ook and State of Illinois, lie-ve invented certain new .and useful Improvements in Underground Subways for streetnilwoys end the Like; and l do hereby declare that the following is e. full, clear, and exact description thereof, `refw ei'ence being had to the accom anying drawings, and to the numerals of re erence marked thereon, which form s pertof this specifi cation. A

This invention relctesto subways built under the streets ol cities for traction-purposes and thiiivention consists in the mst'- ters hereinafter set forth and more srticw' lnrly pointed out in the e pencled c sims.

Among the objectsof tlhe invention is to provide a subwaywhich is so constructed and arranged es to afford ecconomodstions below the' street grade vfor cer tracks oi" e trnction system and also to receive various city and corporation utility appliances, such as electric wires, sewers, pneumatic tubes and other pipes which ere ordinarily buried in the streets in e way'thet necessitates 4the excavation of thel streets to 4gein -sccess thereto. So for as is concerned this feeture ofthe invention, the object of theinvention is to provide within the subwsyepeces end' passages to receive end cer-ry such utility. spe plienees, so arranged that reedysnd' convenient access mcy 'celled thereto for' .the

purpose of repairing, renewinG smi-.supple-I .menting the appliances, sin which-else ei'l'ord convenientmeens for disposing' oeneh utilities over side entrsnceweys to fthe-subwsy orover or beneath intersecting pipes sind wires et the intersectionsoistreets.

traces its consruction metal beams or firders t5, 15 which are .su )ported on the 1 pper ends oli the posts, an yihich in turn supports the material constituting the'rool l The posts 14, 14 are arranged in rows longitudinally of the subway to divide the subway into two parallel passages 20, 2O located near the. center ot' the subway and. two lateral aisles 21, 21, located adiacent to the side walls l1 of the sul' way The said passages or aisles 21I are provided to aceonnnodate the various city and corporation utility appliances which are usually buried inthe street. For instance, racks 24, 2-4 of. any suitable character may be supported on the side walls of Vthe subway to carry electric cables. l have also indicated the location and the manner ot supporting a storni water sewer 25, a high ste-ain and brine mains 27 28 and pneumatic tubes 29. The said .high pressure water niain and storni water sewers are shown as constituting parts of a combined high p lassure and sewer systeni illustrated in my copending ap ilication, Serial No. 442,034, ti on the Gt 'i day oi' July 1908, the high. sure water main being connected with storni sewer by a flush pipe 30, and is -coi'nieeted also with a rlower subsoil sewer 3l by a `flush pipe BZ'and which subsoil sewer receives sewage from adjacent buildings through a building service pipe 33. The storni water sewer receives drain water l'roni the streetthrough a drain water pipo 34.

ln addition to providing` the side or lateral passages 21' to receive some or all of the utility appliances mentioned, l have arv ranged to provide passages or spaces -inst beneath the main rooll 1.2 of the subway, which are designed to receive certain of' said utility appliances under varying local conditions wlnch may be encountered, as will hereinafter more' Yfully appear. A portion of said upper passages or spaces are located bew tween the main roof 12 and horizontal partitions or sub-roots 35, which are made solid to prevent the leakage of water through the main root to the ear passages or sections 20. Between said sunroof andthe main roof are longitudinal spaces or passages 36. The upper parts 37, 37 of the side passage 21 are divide( from the lower parts of said pas- -esages at the .level ot the sub-roots or partiti ins 35 by horizontal beams or girdcrs 40 which atliords support for a portion vot' the utility appliances carried inthe subway. lt will be evident that the spaces 36 and 37 do 'or may coinl'nunicate with each other en-f Therefore, said subway, or transversely across the line. oi' the subway at intersections where the pipes and wires of a transverse street cross the pipes. and wires ot the street beneath. which the subway is'built. This general Inode of 70 arrangingr the intersecting utility appliances is best indicated in Fig. 2, in which is shown intersecting high pressure 1nains26 laid, along the intersecting streets and, in which is also shown upper and lower cable carrying racks 45, 46, one set of' which is designed to carry the cables transversely across the. line ol" the subway and the other of which is designed to carry the cables which extend parallel with the line 'of the subway, and S0 which may or lmay not be diverted upwardly thereto from the lower level vof the lateral aisles or )assages 21. n

As shown in `ig. 5 ingress to and egress from the subway is had through a side en S5 trance 4S which is reached troni a side street entrance 49 by inea-ns ot stairways 50, 50,

Vsaid side 'entrance opening onto a platform 51 at the outside ol' the track, over which passengers alight from and board-trains on the tracks 52. When such side entrance is' provided it will be necessary or desirable to divert or carry such ofthe utility appliances as are inthe side aisles or passages 21 to the overhead passages 36 or 37 and over the en- 95 trainees/48 and side platforms 51. lnlsuch instances the upper side spaces or passages 37 will desirably'be separated from the side passages proper by sub-roofs o r partitions ke the sub-roofs 35 between the ear passages '1.00 and upper passages 36.

As shown in Figs. 1, 2 and 3, the subway is provided with a central ilatlorni 53 located between the car trac s 52 by which the passcngers'leave and. board the train. '105 Said f )latforni'is herein shown as reached by a flig t of stairs 54 leading from a street entrance 55 located at the centerof the street. The manner of entering the tunnel will, ol'

course, depend upon the local conditions prevailing which permit or require the use of a side or centralentrance. 1When the central entrance is used no necessity will ordinarily arise for diverting the wires or iies upwardly between streetintersections. .11.5 Ih' ere a central platform 53 is provided and the car tracks are located throughout the subway at the distance'apartl shown in crosssection in Figs. 1 and 2, such` ital plat-- forni 'inay continue throughout tl the subway either as a platform o' a modified construction of a walk, as shown, n Figs. 3 and Ael, whereby passengers niay alight from. the trains and walk through the. 'subway to another train or to a distant street intersec 12.5

tionv before climbing to the street grade and thus, in the'latter instance, avoid crowded or congested conditions of the Superia-cent streets. 'nother advantage pf the central platform or walk is illustrated in'Fig. 3, illusf 130 engthof 12u and easy transfer l subway, $5

arranged in rows to divide the subway into seance subway beneath a street over which is lol cated an velevated railway and provides a practical and strong JfoundationL for the elel vated structure. ln this instance the trains are approached from platforms 78 78 at the sides of the car tracks, access to which is had through the medium of stairways 79, 79 leading to street, and entrances 8G, S0 located on the sidewalk 59. ln other respects, the construction of the subway is essentially the saine as that heretofore described.

It will be obvious that the details' of con.- struction herein shown may `be modified within the spirit of my invention to adapt the subway to various local conditions, and l do not limit the invention to such structural deof specific claims. For instance, the lateral aisles or passages 2i may be divided from the track passages or sections of the subway by walls and the upper sections 37 of said lateral aisles may be separated from the lower arts thereof by partitions like the horizonta partitions .or sub-roofs Moreover, a single track subway may be constructed with a lateralfpassage lor aisle and the spaces beneath the roof to receive the utility appliances, and said lateralpass'ages or aisles maybe otherwise located relative to tlile track'sections or I claim as my invention- 1.
